Air Conditioning:Hi, what are the reasons that can cause my Mitsubishi Electric Inverter air-conditioner to turn on by itself? The remote control was not facing it, the timer was not on, but it just suddenly turns on by itself.

Air Conditioning Systems:Reset the float switch and air conditioner started. Condensate line was plugged so tried to flush out from float end but did not work so used shop vac to remove debris from drain end. Line is now clean but the air conditioner won't start when the float switch is back in place. Did something get damaged in the process of cleaning the line?
